Effects Of Ground Glass Powder In Silty Soil Stabilization
Jair Arrieta , Carlos Millan and Fernando Jove
Abstract
The article presents the stabilization of soil with glass waste and Portland cement. For this, sedimentary soil originating from the Guabirotuba Formation (Curitiba, Brazil) was used, adding three cement contents in relation to the dry mass of the soil: 3, 6 and 9%. Additionally, 15% of powdered glass residue was the content chosen to add to the soil-cement mixture. The samples were cured in times of 7, 28 and 90 days and submitted to simple compression tests (qu). The results showed that adding the following factors increased the quality of the soil-cement-glass mixtures: cement content, molding dry specific weight and curing time. On the other hand, all strengths are controlled by the porosity/cement ratio (?/Civ) for each curing time. Finally, equations for dosage and estimation of qu were proposed using the ?/Civ index adjusted to an exponent of 0.20.
